[0002] With the development of science and technology, people's living standards are constantly improving, and the types of air conditioners have become more diverse, such as split wall-mounted air conditioners, ceiling air conditioners, central air conditioners, cabinet air conditioners or vertical air conditioners. However, there are many parts on the air conditioner, such as the appearance of plastic parts. When it starts running or just ends running, due to thermal expansion and contraction, these parts will expand and elongate due to heat or shorten due to temperature drop, which will cause the parts to move relative to each other, and friction will occur at the joints between the parts, thereby generating thermal expansion and contraction noise, which greatly reduces the user experience. In particular, vertical air conditioners, because their front panel constitutes the air outlet of the entire air conditioner, are easily affected by the airflow and generate thermal expansion and contraction noise; and the area of ​​the air outlet of the vertical air conditioner is large, and the vertical air conditioner and its front panel are high in the vertical direction. The amount of movement generated when thermal expansion and contraction occurs due to the airflow is also large, and the situation of generating thermal expansion and contraction noise is more serious.

[0041] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 In this embodiment, the air conditioner indoor unit includes a housing 100, and the housing 100 is used to define the appearance of the air conditioner indoor unit. The housing 100 includes a first housing 110 and a second housing 120 that are buckled and connected to each other. The first housing 110 is provided with a snap-on hook 111 extending toward the second housing 120, and the second housing 120 is provided with a slot 121 at a position corresponding to the snap-on hook 111. The snap-on hook 111 is snapped in the slot 121, and at least a portion of the snap-on hook 111 that contacts the slot 121 and / or at least a portion of the slot 121 that contacts the snap-on hook 111 is provided with a noise reduction material.

[0042] It can be understood that the air conditioner indoor unit of the present embodiment includes a first shell 110 and a second shell 120, and since the first shell 110 and the second shell 120 are connected to each other by the snap-in hook 111 and the snap-in slot 121, at least the portion of the snap-in hook 111 that contacts the snap-in slot 121 and / or at least the portion of the snap-in slot 121 that contacts the snap-in hook 111 is set as a noise reduction material, and then, when the first shell 110 or the second shell 120 is heated to expand and elongate or the temperature is reduced to shorten, although the first shell 110 or the second shell 120 will produce relative movement and cause relative movement between the snap-in hook 111 and the snap-in slot 121, the noise reduction material can effectively suppress the generation of friction noise between the snap-in hook 111 and the snap-in slot 121 that are mutually engaged. Therefore, the air conditioner indoor unit of the present embodiment can suppress the generation of noise caused by thermal expansion and contraction at the connection of the two shells, greatly improving the user experience.

[0043] In addition, at least the portion of the card hook 111 that contacts the card slot 121 and / or at least the portion of the card slot 121 that contacts the card hook 111 is provided with a noise reduction material. It can be understood that the portion of the card hook 111 that contacts the card slot 121 (for example, the outer surface of the card head of the card hook 111, the card head of the card hook 111, etc.) is provided with a noise reduction material, or the entire card hook 111 is provided with a noise reduction material, or the portion of the card slot 121 that contacts the card hook 111 (for example, the inner side surface of the stop plate in the following example) is provided with a noise reduction material. , the entire stop plate or the entire inner wall surface of the slot 121 is set as noise reduction material, or the entire slot 121 is set as noise reduction material, or the part of the card hook 111 that contacts the slot 121 and the part of the slot 121 that contacts the card hook 111 are both set as noise reduction materials, or the part of the card hook 111 that contacts the slot 121 and the entire slot 121 are set as noise reduction materials, or the entire card hook 111 and the part of the slot 121 that contacts the card hook 111 are set as noise reduction materials, etc.

[0044] In this embodiment, the noise reduction material is ABS (Acrylonitrile Butadiene Styrene) plastic.

[0045] It can be known that ABS has good noise reduction performance. When it rubs against parts made of other materials, there is a very small friction coefficient between them, thereby being able to achieve the effect of suppressing the generation of friction noise between the snap-fitting hook 111 and the card slot 121 that are interlocked and connected to each other.

[0046] In some other embodiments, the noise reduction material is a rubber material such as nitrile rubber, fluororubber, etc.

[0047] It is understandable that the noise reduction material is set to be a rubber material such as nitrile rubber, fluororubber, etc., which greatly increases the friction between the snap-in hook 111 and the slot 121, effectively avoiding the friction between the snap-in hook 111 and the slot 121, and even if there is relative movement between the snap-in hook 111 and the slot 121, the rubber material such as nitrile rubber, fluororubber, etc. will greatly limit the transmission of noise. Therefore, setting the noise reduction material to be a rubber material such as nitrile rubber, fluororubber, etc. can achieve the effect of suppressing the generation of friction noise between the snap-in hook 111 and the slot 121 that are interlocked and connected.

[0048] In still other embodiments, the noise reduction material is polyurethane.

[0049] It can be known that due to the porous structure of polyurethane, even if there is relative movement between the snap-on hook 111 and the slot 121, the noise reduction material of the polyurethane will effectively absorb the noise, thereby achieving the effect of suppressing the friction noise between the snap-on hook 111 and the slot 121 that are interlocked and connected to each other.

[0050] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 In this embodiment, a clamping block 122 is detachably provided on the second housing 120 at a position corresponding to the clamping hook 111 , and the clamping slot 121 is opened on the clamping block 122 .

[0051] It is understandable that, since the card slot 121 can be provided on the card block 122 , in order to realize that the entire card slot 121 is provided as noise reduction material, the card block 122 can be provided as noise reduction material.

[0052] Furthermore, by setting the clamping block 122 and the second housing 120 as a non-integrated detachable structure, the material of the clamping block 122 can be upgraded separately, that is, only the clamping block 122 is set as a noise reduction material. Therefore, it will not cause too much material cost increase, and the cost of the air conditioner indoor unit of this embodiment can be effectively reduced.

[0053] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 In this embodiment, the card slot 121 on the card block 122 has a card slot 1221 opened toward the first shell 110 and a card slot wall 1222 set facing the first shell 110, the card hook 111 passes through the card slot 1221 and extends into the card slot 121, and the card hook 111 is hooked on the inner side of the card slot wall 1222 to limit the first shell 110 from moving in a direction away from the second shell 120.

[0054] It can be understood that by extending the snap hook 111 through the snap slot 1221 into the snap slot 121, and hooking the snap hook 111 on the inner side of the snap slot wall 1222, the snap connection between the snap hook 111 and the snap slot 121 and the snap-fit ​​connection between the first shell 110 and the second shell 120 can be achieved.

[0055] Reference Figure 6 and Figure 7 In this embodiment, the card slot 121 has a communication port 1225 on the card block 122 , which is arranged opposite to the card slot 1221 , and the communication port 1225 is connected to the card slot 121 .

[0056] It should be noted that, since the depth of the slot 121 in the direction in which the first housing 110 and the second housing 120 approach or move away from each other needs to be set deeper to prevent the snap-in hook 111 from being unable to fully extend into the slot 121 and snap-in to the inner side of the snap-in slot wall 1222, the snap-in hook 111 cannot contact the inner side of the slot wall of the slot 121 that is arranged opposite to the snap-in slot opening 1221 during assembly or when the air conditioner indoor unit is assembled and operated. Furthermore, while ensuring that the snap-in hook 111 and the slot 121 can be assembled smoothly, by providing a connecting port 1225 on the snap-in block 122, the materials required to construct the snap-in block 122 can be further reduced, and the production cost of the air conditioner indoor unit can be further reduced.

[0057] Reference Figure 3 , Figure 4 and Figure 5 In this embodiment, a mounting frame 123 is provided on the inner wall of the second shell 120 at a position corresponding to the snap-on hook 111, a mounting groove 1231 is provided in the mounting frame 123, and the mounting groove 1231 on the mounting frame 123 has a first groove 1232 facing the first shell 110, the snap-on block 122 is provided in the mounting groove 1231, and the first groove 1232 is provided relative to the snap-on groove 1221; and a limiting body 1233 for limiting the movement of the snap-on block 122 toward the first shell 110 is provided on the inner wall of the first groove 1232.

[0058] It is understandable that, by providing the mounting frame 123 and the mounting groove 1231 on the inner wall of the second housing 120, the clamping block 122 can be embedded in the second housing 120. And by providing the first notch 1232, the clamping hook 111 can be allowed to pass through the mounting frame 123 and extend into the clamping groove 121 to be hooked with the clamping groove 121.

[0059] In addition, after the shell 100 is completely assembled, that is, the first shell 110 and the second shell 120 are snap-fitted and connected to each other, in order to prevent the snap-fit ​​block 122 from being pulled out of the first slot 1232 by the first shell 110 through the cooperation of the snap-fit ​​hook 111 and the slot 121, a limit body 1233 can be provided on the inner wall of the first slot 1232 to effectively ensure the connection stability of the snap-fit ​​hook 111 and the slot 121, the first shell 110 and the second shell 120.

[0060] Reference Figure 3 , Figure 4 and Figure 5 In this embodiment, the mounting groove 1231 on the mounting frame 123 further has a second groove 1234 opening toward the inside of the second housing 120 , and the second groove 1234 is used to allow the clamping block 122 to be installed in the mounting groove 1231 .

[0061] It is understandable that, through the second notch 1234, the clamping block 122 can be easily installed on the second shell 120 when the air conditioner indoor unit is assembled at the factory, thereby ensuring the assembly efficiency of the air conditioner indoor unit at the factory.

[0062] Reference Figure 3 , Figure 4 and Figure 5 In this embodiment, the clamping block 122 is provided with an elastic hook 1223 extending from the first slot 1232 out of the mounting frame 123 and extending toward the inner wall surface of the second shell 120; and, a clamping protrusion 1235 is provided on the outer surface of the side slot wall of the mounting slot 1231 at a position corresponding to the elastic hook 1223, and the elastic hook 1223 is hooked on the clamping protrusion 1235.

[0063] It can be known that, by providing the elastic hook 1223 and the clamping protrusion 1235 , the detachable connection between the clamping block 122 and the second housing 120 can be achieved.

[0064] Reference Figure 3 , Figure 4 and Figure 5 In the present embodiment, a limiting through groove 1236 is provided on the side groove wall of the mounting groove 1231 at the first groove opening 1232, and the limiting through groove 1236 is connected to the inner and outer side surfaces of the side groove wall of the mounting groove 1231, and the limiting through groove 1236 is arranged corresponding to the elastic hook 1223, and the elastic hook 1223 has an extension portion 1224 extending from the first groove opening 1232 to the mounting frame 123, and the extension portion 1224 is embedded in the limiting through groove 1236.

[0065] It is understandable that by embedding the elastic hook 1223 in the limiting through slot 1236 , the movement of the clamping block 122 in the installation slot 1231 can be limited to further ensure the connection stability of the clamping block 122 detachably installed on the second housing 120 .

[0066] Reference Figure 3 , Figure 4 and Figure 5 In this embodiment, the limiting through slot 1236 and the extension portion 1224 are arranged in a direction perpendicular to the direction in which the first housing 110 and the second housing 120 move away from each other, so as to limit the movement of the clamping block 122 toward the first housing 110 .

[0067] It can be understood that, on the basis of ensuring the connection stability between the snap-in block 122 and the second shell 120, by arranging the limiting through slot 1236 and the extension portion 1224 in a direction perpendicular to the first shell 110 and the second shell 120 moving away from each other, the movement of the snap-in block 122 toward the first shell 110 can be limited, and the snap-in block 122 can be further prevented from being pulled out of the first slot 1232 by the first shell 110 through the cooperation of the snap-in hook 111 and the slot 121, so as to effectively ensure the connection stability between the snap-in hook 111 and the slot 121, the first shell 110 and the second shell 120.

[0068] Reference Figure 5 In this embodiment, at least one supporting rib 1237 is disposed at the bottom of the mounting groove 1231 disposed relative to the second groove opening 1234 .

[0069] It can be understood that the support rib 1237 is used to support the clamping block 122 to reduce the contact area between the clamping block 122 and the bottom surface of the installation groove 1231 set relative to the second groove 1234, so as to effectively suppress the generation of noise caused by the friction between the clamping block 122 and the aforementioned bottom surface of the groove.

[0070] In addition, the number of supporting ribs 1237 can be set to be multiple.

[0071] In the first variant embodiment, the first housing 110 and the engaging hook 111 are detachably connected.

[0072] It is understandable that by setting the snap-on hook 111 and the first housing 110 as a non-integrated detachable structure, when the material of the snap-on hook 111 needs to be set as a noise reduction material, the material of the snap-on hook 111 can be upgraded separately. Therefore, it will not cause too much increase in material cost, and can effectively reduce the cost of the air conditioner indoor unit of this embodiment.

[0073] In the first implementation of this variant embodiment, a screw hole is provided at the position where the snap-on hook 111 is provided on the first shell 110, and a mounting through hole is provided on the snap-on hook 111. The screw is passed through the mounting through hole and connected to the screw hole, so that the snap-on hook 111 can be detachably connected to the first shell 110.

[0074] In the second embodiment of this variant embodiment, a snap-in interlayer is provided at the position where the snap-in hook 111 is provided on the first shell 110, and a snap-in plate is provided at the tail end of the snap-in hook 111. The snap-in hook 111 is detachably connected to the first shell 110 by snapping the snap-in plate into the snap-in interlayer.

[0075] Combine the following Figure 1 , Figure 2 and Figure 8 ,as well as Figure 4 , Figure 5 , Figure 6 or Figure 7 , to describe in detail the vertical air-conditioning indoor unit of this embodiment.

[0076] In this embodiment, the air-conditioning indoor unit of the above embodiment is included, and the beneficial technical effects of the air-conditioning indoor unit of the above embodiment are also possessed by the vertical air-conditioning indoor unit of this embodiment.

[0077] Reference Figure 1 and Figure 2 In this embodiment, the first housing 110 may be a front panel, and the second housing 120 may be an air inlet grille.

[0078] In some other embodiments, the first housing 110 may also be a top cover of a vertical air conditioner indoor unit, and the second housing 120 may be a front panel / air inlet grille.

[0079] Reference Figure 1 and Figure 2 In this embodiment, the front panel and the air inlet grille are both arranged in the up-down direction.

[0080] Reference Figure 1 and Figure 2 In this embodiment, the front panel is buckled and connected to the front of the air inlet grille, the snap hook 111 can be set at the rear edge of the front panel, and the snap slot 121 can be set at the front edge of the air inlet grille. The snap slot wall 1222 is located below the snap slot 1221, and the snap head of the snap hook 111 extends downward.

[0081] In addition, in order to ensure the connection stability between the front panel and the air inlet grille, the number of snap-in hooks 111 can be set to multiple, and multiple snap-in hooks 111 are arranged on the front panel in the up and down directions; the number of slots 121 corresponds to the setting of the snap-in hooks 111, and multiple slots 121 are arranged on the air inlet grille in the up and down directions.

[0082] And, refer to Figure 4 , Figure 5 , Figure 6 or Figure 7 ,as well as Figure 8 The width of the lower part of the snap-in slot 1221 is smaller than the width of the upper part. Such a structure with a larger upper part and a smaller lower part can limit the snap-in hook 111 by the snap-in slot 1221 after the snap-in hook 111 is snapped into the slot 121, thereby ensuring the connection stability between the snap-in hook 111 and the slot 121.

[0083] Furthermore, the engaging groove wall 1222 may also extend on the left inner wall side or the right inner wall side of the engaging groove 1221 to make the width of the lower portion of the engaging groove 1221 smaller than the width of the upper portion thereof.
